遷移的Windows Phone 7.1的Windows Phone 8的錯誤

Question

我想我的應用程序從Windows手機7.1遷移到Windows Phone 8。 我有這樣的錯誤：

Error 1 Cannot resolve dependency to assembly 'System.Windows.Interactivity, Version=3.9.5.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' because it has not been preloaded. When using the ReflectionOnly APIs, dependent assemblies must be pre-loaded or loaded on demand through the ReflectionOnlyAssemblyResolve event. D:\project\WP8\Vp.Front.WinPhone7-mango\Vp.Front.WP7Mango\Auth\LoginPage.xaml 1 1 Vp.Front.WP7Mango 

我怎樣才能解決此問題：

Answer 1

只需刪除dll並從8.0目錄重新添加。 C:\Program Files (x86)\Microsoft SDKs\Expression\Blend\Windows Phone\v8.0\Libraries\Microsoft.Expression.Interactions.dll
